playing videos in JATOS from lab.js file
I wrote an audiovisual experiment in lab.js.
I want to do a pilot study by using the free server of JATOS (Thank you for that! ). When I upload my study and run it, the video's are delayed. It gives no video at all, or a black screen first and then shows the video, but my audio and video are separate (and it shows synchronized in lab.js without the black screen) so audio and video are completely off when I run it in JATOS. Does anyone have experience with this or knows how to solve it?
It runs without problems in lab.js.
The videos are .mov files, but I also tried it with a .mp4 file, that doesn't change anything.
There are 20 different videos, but they are all relatively small (between 500-900kb). The videos are integrated in the .json file
I also tried to make a very basic experiment to see if I could just get a video to run. So i made a lab.js file with a start screen and then 1 video, but this has the same problems. (I wanted to upload the zipfile here, downloaded from lab.js but it gives me error 431?)
I tried to run it in chrome and Safari, both have the same problems.
It would be amazing if someone could help me with this issue! Thanks!
